Description

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a liquid container from which the liquid contents can be dispensed without spillage with the container in an inverted position, and specifically to a container for combustion engine oil that can be used in very limited engine compartment spaces to dispense oil into the engine without spillage through the use of a manually actuated dispenser mounted within the container.
2. Description of the Prior Art
The use of small hand-held containers for dispensing liquids often involves aligning the spout of the container with an opening that is to receive the liquid and inverting the container to empty its contents. When dealing with combustion engines as are found in aircraft, boats or automobiles and other machines, oftentimes the engine opening for receiving a liquid such as oil is located in an inaccessible area without sufficient maneuvering space that makes pouring awkward or almost impossible without spillage. The end result is more often than not, spillage of the oil around the engine compartment while trying to pour the oil into the proper engine opening. Devices for facilitating emptying of an oil can container into an engine oil input have been shown in the prior art. For example, U.S. Pat. No. 4,497,351 issued to Garcia on Feb. 5, 1985 shows an apparatus for dispensing oil from an oil can which is used by penetrating the bottom of the oil can after the apparatus has been attached to the oil inlet. Such an apparatus requires sufficient engine compartment space to place the oil can over the cutting element and to forcibly rupture the can bottom which would be difficult in a cramped space. Likewise U.S. Pat. No. 4,289,255 issued to Strampe on Sept. 15, 1981 shows an oil filter cap which is mounted on the rocker cover in an internal combustion engine, which again requires sufficient space to maneuver the oil can over the can opening mechanism to sufficiently penetrate the can opening to empty the can.
The present device overcomes the problems of the prior art by providing a device that can be used for dispensing engine oil into an engine oil input which requires no more room than basically the length of the container itself and which can be actuated in an inverted position after the spout of the container has been placed within the engine oil inlet, eliminating any possibility of spillage.
SUMMARY OF THE INVENTION
A hand-held liquid container having a self-contained dispensing actuator that permits dispensing of the liquid therein to begin after the container has been rotated to an inverted position. The liquid container includes a hollow body, a spout, a frangible seal such as foil disposed over the spout opening, sealing the liquid contents therein, and a conventional threaded screw-type cap that is placed over the spout for storage and transit.
Inside the container is disposed a dispensing plunger having an elongated shaft that runs essentially the length of the container from the container base to near the upper rim of the spout, the plunger including a cutting head uniformly formed with one end of the shaft at a predetermined angle. The cutting head has a crescent-shaped body with a knife-edge upper surface forming an upper ridge on top of the crescent-shaped body and non-cutting retainers uniformly formed below the knife-edge extending in furtherance of the crescent-shape preventing the plunger from leaving the container after the frangible seal has been broken. In an alternate embodiment, the non-cutting retainers can be eliminated in that the plunger end tip is heat fused to the bottom floor of the container in an area having a movable recessed portion for activating the plunger.
The base wall or floor of the container in the area where the plunger shaft end tip resides (opposite end from the cutting head) includes, in one embodiment, a small aperture which permits a portion of the plunger shaft to be disposed therethrough, the container area housing the aperture being somewhat recessed from the plane of the container bottom. A flexible sealable sheet is attached over the recessed area so that the plunger end tip is completely housed in a compartment sealed from the outside environment. The flexible sealing sheet is thus substantially in engagement with the end tip of the plunger shaft which allows the shaft to be manually actuated by a finger causing the plunger cutting head to move toward and pierce the spout seal over the spout opening while the container is inverted. The cutting head pierces the frangible seal in substantially a crescent-shape so that a portion of the seal remains attached to the spout rim preventing the seal from falling into the engine oil input while allowing the oil to flow freely from the container in an inverted position. The retainers on the cutting head prevent the plunger from falling out of the container.
In an alternate embodiment, the bottom floor or wall of the container, which normally is made of a molded unitary plastic-like material, may include a designated area of increased flexibility that can be manually depressed with some movement to permit actuation of the plunger when the container is inverted. In this embodiment, the recessed area of the floor having an aperture for the plunger end tip is eliminated.
In still another alternate embodiment, the plunger end tip is heat fused on the inside bottom wall of the container in a specified area that has a circular depressible, flexible location in which the circular raised portion receives the end tip of the plunger. By heat fusing the end tip of the plunger shaft to the bottom container wall, the non-cutting areas on the head of the plunger can be removed since the plunger will not leave the container. In this embodiment the outside raised area of the container bottom is depressed and being flexible allows the raised portion to move inwardly a sufficient amount to move the plunger head thereby tearing the seal over the mouth of the container allowing the oil to be dispensed.
The container body may be made of any suitable liquid impervious material and is usually a heavy grade molded plastic.
To operate the invention, first the oil cap is removed from the opening in the valve cover on the engine into which oil is to be dispensed. The oil container cap is removed. The oil container may be inverted with the spout disposed within the oil inlet opening. At this point in time, the end tip of the plunger shaft is then depressed manually through the container bottom with a finger which causes the foil seal over the spout to tear in a substantially crescent-shape, permitting the oil in the container to pour freely into the engine. Once the container is empty, it can be easily removed and the cap replaced and the entire container with the actuating plunger disposed.
Although the invention is shown used for engine oil dispensing, the invention can also be used with other liquids in a suitable container for dispensing brake fluid or any other liquid that must be dispensed in very closed spaces without sufficient room for proper alignment and inversion of the dispensing container.
It is an object of this invention to provide an improved liquid dispensing container which permits inversion of the container and dispensing in very limited spaces without spillage.
It is another object of this invention to provide an improved oil dispensing container that has a self-contained dispensing plunger which permits dispensing after the container has been properly positioned with the container spout within the engine oil intake opening to prevent spillage.
And yet another object of this invention is to provide a non-complex, low cost oil container that includes a dispensing device to prevent spillage of the oil in limited space engine compartments.
In accordance with these and other objects which will be apparent hereinafter, the instant invention will now be described with particular reference to the accompanying drawings.

PREFERRED EMBODIMENT OF THE INVENTION
Referring now to the drawings, and in particular FIG. 1, the present invention is shown generally at 10 comprised of a liquid impervious container 12 useful for holding oil or other liquids, the container body 12 having a spout 12a and a recessed base portion 12b. Disposed within the container is a plunger 16. The conventional container cap 14 is mounted over spout 12a.
FIG. 2 shows an end view again showing the plunger 16 disposed within.
Referring now to FIG. 3, invention 10 also includes a frangible seal 18 disposed across the opening of spout 12a that prevents the liquid oil inside from spilling out of the container after the cap 14 is removed preparatory for dispensing the oil. The container 12 can be inverted with the seal 18 thereon and no liquid will leave the container.
The plunger 16 includes a cutting head 16a which is disposed relative to the shaft of plunger 16 so that the uppermost portion of the cutting head 16a can engage the frangible seal 18 at an initial single edge. This aids in the tearing and cutting action of the seal when the device is actuated.
The bottom wall 12b of container 12 includes a recessed portion through which the plunger 16 shaft is disposed in an aperture 12bb and the recessed portion 12b. In order to prevent oil from leaking from the container, a flexible seal 20 is mounted over the recessed portion 12b which allows for depression of plunger end tip 16 for actuating the device.
FIG. 4A shows the upper portion of the plunger 16 and the cutting head 16a which includes a knife edge 16b along the upper portion of the cutting head. It is the knife edge 16b that will slice through the frangible seal 18 as shown in FIG. 3. The plane of the cutting head 16a may be at an angle less than 90 degrees from the shaft so that the center of the crescent shaped cutting head engages the frangible seal first. In this embodiment the cutting head includes projecting the retaining members 16d which do not cut the seal but which engage the portion of the seal that has not been cut to prevent the plunger from falling out of the container when the container 12 is in an inverted position while dispensing oil from the container. The retainer 16d may be eliminated in another embodiment discussed below.
FIG. 4B shows the top plan view of the cutting head 16a which reveals that it is a partially circular or crescent-shaped of approximately 270 degrees which allows the foil seal to be ripped only in those areas exposed to the knife edge 16b on the cutting head 16a. Thus the seal 18 cannot fall into the engine opening since it will still be attached partially to the spout.
FIG. 4C shows an alternate embodiment of the plunger 22 which has a cutting head 22a and a serrated upper edge 22b for cutting.
FIG. 5 shows the frangible foil seal 18 in an exploded view which is affixed and sealed by a suitable adhesive around the upper rim opening of spout 12a. The physical relationship of the cutting head 16a is shown near the top of the spout in the sealed position.
FIG. 5A shows the condition of the seal 18 after the cutting head on the plunger 16 has been actuated. The uncut portion of the seal 18 prevents the torn portion of the seal 18 from falling into the engine oil compartment and also engages retainers 16d (see FIG. 4A) preventing the plunger 16 from leaving the container.
FIG. 6 shows the container 12 in an inverted position having been actuated by use of a finger that depresses against the end tip of rod 16 forcing the cutting head 16a against the frangible seal 18 forcing it to rip in a crescent-shape. The oil is then free to flow from the container. The container has been pre-positioned so the spout is in the oil inlet opening in the engine oil compartment thus preventing any spillage.
FIG. 6A shows the container 12 having a recessed bottom wall portion 12b and in the recessed portion 12b an aperture 12bb which receives a portion of the shaft of plunger 16. The fit between the aperture 12bb and the diameter of the shaft 16 is such that it is a snug fit to prevent excess oil from leaking into the recessed chamber but with sufficient space to prevent a liquid pressure lock when depressing the flexible sheet. However a sealing flexible sheet 20 is affixed to the base of the container 12 to ensure that the entire container is sealed. The flexible sheet 20 also permits actuation or pushing on the plunger 16 shaft end tip for actuating the device.
FIG. 6B shows an alternate embodiment of the container 24 having on its bottom wall, a thin resilient portion 24a which again can be used for flexibly depressing against the end tip of plunger 16. The flexible portion 24a of the bottom wall is achieved in the molding process by making the wall portion thinner than the surrounding wall of container 24. A support fixed to the thin resilient portion on the inside wall surrounding the shaft end tip prevents lateral movement of the shaft end tip.
Referring now to FIG. 7 an alternate embodiment which is the preferred embodiment of the invention is shown in which the invention 22 includes a container 24 similar to the one already described herein having a cutting plunger 26 with cutting head 26b. The end tip 26a of plunger 26 is heat fused to a predetermined recessed area 24a formed unitarily in the bottom floor of container 24. The recessed area 24a is defined by a circular ridge around the heat fused end tip 26a of the plunger which firmly holds it in place. In that the bottom floor of container 24 is somewhat flexible, the recessed area 24a may be depressed from the outside so that it extends to area 24b which is a sufficient distance to allow the plunger head 26b to tear the seal across the top of the container allowing the oil to be dispensed when the container 24 is in an inverted position.
FIG. 8 shows the location of the shaft 26 of the plunger in a recessed area that is defined by a raised portion 24b inside the container.
In FIG. 9 the recessed portion 24a is shown surrounded by a depressed area 24b defining the actuating mechanism for the container.
Although the invention has been shown for use as an oil container to prevent oil spillage in an engine compartment, other fluids can be used in the container for dispensing in likewise closed or limited space areas where spillage is not desirable.
The instant invention has been shown and described herein in what it is considered to be the most practical and preferred embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
